Clutch questions

I have two questions concerning the installation of a clutch. I am mating a t-18 with a 304 in a '67 Scout 800a. The original transmission was a t-90 three-speed. I am building this '67 800a out of a parts pile, and much is unclear to me.

First question: I have two different models of the shaft that passes through the bell-housing, and I don't kow which is the proper one. I could not use the original bell-housing because the hole is too small for the bearing retainer on the four-speed. That is the only difference I can detect between the two bell-housings.

The difference between the two shafts is the upright arm that is welded to the round shaft. On one, the upright arm is bent so that it is offset away from the bell-housing. It was on the original three-speed bell-housing.the other has a bend and an offset toward the bell housing. It came with the four-speed bell housing that I scrounged up. The first one (original) is set up so as to link up with the clutch-pedal pivot rod. I am pretty sure that this is the one I should use. Any insight would be helpful.

The second question: I have read carefully through the long thread in the archive about clutches, collars, and throw-out bearings. I think I understand what I should be using. Here is my take: I am using an 11" clutch that resembles the borg and beck long model illustrated in that thread. I think that I interpret the thread correctly that I should use the "long" collar. The thread also talks initially about neutral balancing the flywheel and clutch together. Later in the thread, however, the view seems to change based upon additional info. So, question: should I do the balance thing or not?

I hope this is not too confusing. In sum, I am going to use the original bell-housing shaft, an 11" clutch, and the "long"collar. I am still in the dark about the balancing question.

If anyone can make any sense out of this, I would appreciate your insights. Pineneedle
